multiparameter attributes error for date_select

I added just this one piece of coding to app and now it doesn't allow anyone to register. I receive the following error: 1 error(s) on assignment of multiparameter attributes. The title of the error page is "ActiveRecord::MultiparameterAssignmentErrors in UsersController#create". I am not sure how to fix as other posts were not helpful unfortunately. Anyone have some solutions?

new.html.erb: 

<div class="field">
                    <%= f.label :birthday %>
                    <%= f.date_select :birthday, :start_year => 1995, :end_year => 1930 %>
                    </div>

users_controller:

def create
    @user = User.new(params[:user])
    if @user.save
      UserMailer.registration_confirmation(@user).deliver
      session[:user_id] = @user.id
      redirect_to root_url, notice: "Thank you for signing up!"
    else
      render "new"
    end
  end

development.log:

The actual problem was the value in database was on VARCHAR, and instead it should be DATE. Now it works fine.

First make sure that the type of the birthday should be Date.

Here in parameters, the values for birthday is going like below.

"birthday(1i)"=>"1995", "birthday(2i)"=>"3", "birthday(3i)"=>"22"

But the type of the field id Date. So as i think, before updating the birthday field, we need to generate the appropriate date object and then need to update the object.

@user.birthday = Date.strptime("#{params['birthday(3i)']}/#{params['birthday(2i)']}/#{params['birthday(1i)']}", "%d/%m/%y")

Now save the object and hopefully it will not raise any error this time.

If still having error, pls let me know.
